Abstract

In the present paper we analyze the diffusion coefficients, D, of the component elements, measured recently in CoCrFeMnNi high-entropy alloy. Our analysis, based on the use of the correct form of the well-known semi-empirical rules (law of corresponding states) i.e. plotting the logarithm of the normalized (dimensionless) value of D vs. the reduced temperature, confirms the sluggish character of the diffusion as compared to the pure reference metals, but this behavior can mostly be attributed to a more or less temperature independent factor in the diffusion coefficients i.e. to correlation effects rather than the higher activation energies.
